Beneath the spindle, J tit its Lilli er there is placed, 1g 2; pendenz {swim of we cap N, a epig el Spring the l of which rests m1 e preeser of the spring on the diaphragm L next may he foreedinward to regulate the pressure the wusteport F of the case A by a screw, U, threaded into the end of the cepster'n N. (See the spring 55 will be regulated by the screw U. to hold the diaphragm L to its seat lend hold the diaphragm K away from its seat k, to a1- press the vulve stenilow a proper quantity of gas to pass from the churnher B, port E, and outlet E, as indicated by the arrows in Fig. 2,2116, through the pipe G to the boiler-furnace at any desired predetermined pressureof steam to'be maintained in the boiler. Should the boilenpressure rise above this normal limit, the steam-pressure throi'igh pipe It on the diaphragm 0 will de- .l' and close the diaphragm K partly or wholly to its seat is, and thereby out off the excessive supply of gas to the boiler-furnece,'snd at the same time the item J will depress the diaphragm L and open he port h to the chamber B, to allow the gas to escape or wuste at the outlet F through the pipe H, and thus prevent the necking up of gas-pressure in the supply-pipe D. When he steempressure lowers'to the-normal limit,

\ luregui L to its seat lend cut oil the waste of ,u-s, and the diaphragm 0 will simultaneously opened, .lo ellowges to again pass to the boiler-furnace, as shove described. The valvestem 3 end diaphragm-valves K L may ,be so arranged that e proper supply of gas will pass to the furnace, while the excess of gas coming under pressure through the pipe D will. he allowed to escape at the waste-outlet F,

lt is obvious that the cliuphragins KL not only not us valves to pass the gas to the furnace and to waste, but the diephrsgms serve no partitions which entirely cut oil the gas iron: the spaces at the ends of the case A, in

which. thediephrngm O and spring S are placed; hence these parts 0 S cannot be affeet-ed by the gas, end will respond very sensitively to changes in the steam -pressure,

whereby said. pressure may be closely coutrolled,

iii-nether important feature of this construction of the governor is, that the diephraguis L open all around their respective seats is Z, and give e prompt l'ull exit or passage of gas with a very slight movement of the diaphragm, and this prompt opening and closure of the opposite diuphrugms K L by a slight movement of them materiallyincreases or improves the sensitiveness of the governor, and also allows a much less bulky governor to perform the work of a larger more expensive one otherwise arranged.

The distinctive features ofour invention may easily be embodied in a governor having two or more diaphragm valves controlling ports opening to e common outlet at opposite ends of the governor-case, and as showuiu and of the drawings, wherein the l Figs. 0

spring S will expand to close the die 'ive pressure of'stemn in the valves L on a stem, J, are noted on by e steam -.pressed diaphragm, 0, es above-described; but instead of the spring S we show a counterbalance-weight, s, on an arm or lever, s, connected with the valve-stem J,which The operation is as follows: The tension of projects through a stuffing-box, N, on the lower cap, N, for utilizing the gravity of the weight to counteract the pressure on thediaphragin 0n the valve-stem J, and at short distances from the valves K'L, there are fixed the valves K" L", respcctively,which are adapted to close on seats is 1', formed. at the open ends of an nular ports E E, which are formed in Corr 0. These valves K, Lore seated at 70 Z, like the valves K L in Fig. 2-.

tracte'd portions of the case A, and open also into the outlets E F, respectively. These valves or diaphragms K L" consist preferably of two plates-one of rubber, the other of metal-and are perforated, as at 70 l, respect ivel y, so that gas or other fluid may freely pass through them to the imperforete outer die.- phragm-va-lves, K L, to escape past the seats k Z into ports E F, while the fluid is escaping past the seals k 21" into the ports E B, thus are suring it perfect balance of the opposite pairs ofjvelves, and allowinge inuch quicker 0pening for escape of the gas or other fluid to the ports'E' F of the governor.

In Fig. 3 the lower valves, L L, are open for exit'of gas at the weste-outletli,end the upper valves, K K are closed,as-when excessboiler on the diephragmO has cut off the supply of gas to the boiler through the outlet ll, the passage of the gas through the, open vulve's being indinoted by the arrows.

It is obvious that three or more velveemey be arranged at each end of the governor in u suitably-contracted case, and in every instance all the valves except the outer ones, K L,will

be perforated for the passage of the gas or fluid to secures bolonce'ol the entire valve system, s above explained.

This'governor may be used for reducing the. pressure of steam to insure a regular pressure at e point of delivery as well as for sup, plying gaseous fuel to furnaces, as herein more particularly described.
